YARN-CLEANER FOR SPOOLlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 448,622, dated March1'7, 1891.

Application filed May 31, 1881. Serial No. 34,576. (No model.)

To all whom it may concern.-

Be it known that I, JOHN M. CURTIOE, of Lowell, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Yarn-Cleaners for Spooling-dachines; and I do herebydeclare the same to be described in the following specification, andrepresented in the accompanying drawings, of which- Figure 1 is a topview, Fig. 2 a front elevation, Fig. 3 a vertical and longitudinalsection, and Figs. at and 5 transverse sections, of one of my improvedyarn-cleaners, the plan of section of Fig. 5 being taken 011 the dottedline 0c 00 of Fig. 2, and that of Fig. 4 being taken on the dotted liney y of Fig. 3. Fig. (5 is a side view, and Fig. 7 a top view, of itsautomatic stop-gate, to be hereinafter described.

XVhile being spooled, yarn, after having been spun byaring-spinningframe, is usually drawn between parallel edges arranged very closely toeach other, they operating to separate from it anysmall bunches orextraneous matters. hen a bunch in the yarn may be so large as tobecomecaught by the cleaner, in a manner to prevent the yarn from being drawnthrough it, an attendant, rather than remove the bunch by hand from theyarn, will sometimes slip the yarn out of the cleaner, so as to allowthe bunch to pass to the spool, the yarn being next dropped into placein the cleaner. To prevent this from being done, cleaners have beendevised in which the slot is closed by a detent or dog,so as to preventthe dislodgment ofthe thread. My invention relates to cleaners havingsuch dogs; and it consists in a cleaner having the constructionhereinafter pointed out.

In the drawings, the adjustable portion of the yarn-cleaner is shown atA and its support-piece at The upper edge a of the portion A is inclinedto its cleaning-edge l), which is directly over the parallel fellow edgeact the support-piece and forms therewith ahorizontal slot, and there isbetween the upper and lower edges a b of the portion Aanoth'er and shortedge (Z, which makes an obtuse angle with the edge 6. The portion A hasprojecting down from it a tongue e, which is arranged between andagainst parallel guides ff, projecting from the front of thesupport-piece, such tongue having a short vertical slot g in it toreceive the shank of a set-screw it, used to confine the tongue to thesupport-piece B. The said support-piece ischambered, as shown at h, toreceive the automatic stop-gate O, the cap D of the chamber havingprojecting from it the supporter E, upon which the yarn travels whilebeing cleansed, said supporter being at its ends provided with inclinedsurfaces 6' 6 for the purpose of keeping the yarn in proper positionupon it, (the said sup porter.) This supporter E is in front of theguide-slot 1), between the edges 1) c, and supports the thread on itsway to said slot. The cap is held to the support-piece, not only by thestop-gate pivot, which extends into the cap, but by a set-screw s, whichgoes through the cap and is screwed into the support-piece. By havingthe yarn-supporter and the cap of the stop-gate chamber connected or inone piece the supporter becomes sustained by and removable with the cap,such being ad vantageous for permitting ready access to be had to thecleaning-edges or the stop-gate for the separation therefrom of fibrousaccumulations or for other purposes. The stop-gate, formed as shown,turns upon a stationary pivot i, arranged as represented, the nose k ofthe gate being borne against the edge d by the gravitating power of thepart Z of the gate. Projecting from each side of the said nose is a spurm. The yarn on being dropped upon the upper edge of the portion A willpass down such against the nose of the gate, which by the pressure ofthe yarn will be tripped and will allow the yarn to pass into the spacebetween the gage-edge b and the fellow cleansing-edge c, the gravitatingpower of the gate causing the nose to be thrown up instantly afterwardto the edge cl. The gate when against the said edge will operate toprevent the yarn from being drawn out from under the portion A, thespurs preventing additional obstruction thereto. As the thread is woundabout the spool, it is drawn over the supporter E and then through theslot 1). As it is thus wound, it travels lengthwise of the slot andtraverses the supporter from end to end, allowance being thus made forthe increase of thread upon the spool, and the thread not running overone line of the supporter but moving along it does not cut the latter.3y this construction the old form of yarncleaner is modified so that thedetent is hung in such a way that the attendant cannot tainper with it.The detent is entirely concealed except at the small point where itcrosses the guide-slot. This point is so narrow that any instrumentinserted to move the detent would of itself fill the slot.

I am aware that a yarn cleaner or guide having a vertical slot which isvaried in width by an adjustable blade is old; also that it has beenproposed to use therewith a hooked detcnt to prevent the yarn from beingpulled out, and I lay no claim to any such invention.

\Vhat I claim isthe support-piece, substantially as shown and 30described.

JOHN M. CURTICE.
